Dispersion

This program calculates and plots the dispersion relations of elmag. wavesin a 1D photonic crystal (PhC) for both "s" (TE) and "p" (TM) polarization states;The 1D-PhC has a unit cell made of two different dielectric materials (known as Bragg mirror);The propagation angle in one medium is taken as...

The Ejs Wave Packet model displays the motion of an approximate wave packet. The simulation allows an arbitrarily wave packet to be created. The default dispersion relation, with the frequency equal to the wavenumber, results in a wavepacket that does not spread. The amplitude, maximum and... Platforms: Mac
